Citrulline malate

The most commonly studied form for exercise performance. Benefits appear slightly greater than citrulline alone, possibly due to the malate contribution.

A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.

Several studies show increased repetitions to failure in resistance exercise (typically 1–3 extra reps per set) and reduced muscle soreness 24–48 hours post-exercise. The contribution of malate versus citrulline alone is not well isolated in most trials.

• Increased repetitions to failure in resistance training
• Reduced delayed-onset muscle soreness
• Malic acid may support aerobic energy production

6–8 g taken 30–60 minutes before exercise. Look for 2:1 citrulline-to-malate ratio.

• Mild GI discomfort
• Sour taste

Generally well tolerated. Verify the ratio — some products labeled citrulline malate contain less than the 2:1 ratio used in studies.

It is unclear how much of the benefit comes from malate versus citrulline. The 2:1 ratio means 8 g of citrulline malate provides roughly 5.3 g of citrulline.
